ArcGlobe Draw Rectangle OpenGL

I've only successfully drawn a rectangle by having a custom globe layer rasterized, therefore using the 2D display basically to draw using the 2D symbols.

Inside of my DrawImmediate function, I have been able to draw a rectangle with GeographicToGeocentric to convert Lat/Lon coordinates to Geocentric but the Quad draws through the globe and is not 'draped' on it.
